F.1. Extending Backup and Restore Behavior

The backup and restore system within Tungsten Cluster is handled entirely by
the replicator. When a backup is initiated, the replicator on the specified
datasource is asked to start the backup process.

The backup and restore system both use a modular mechanism that is used to
perform the actual backup or restore operation. This can be configured to
use specific backup tools or a custom script.
